Hi!  When trying to upgrade package `snap 6.9.0` from Guix commit `404f6953`
to `snap 7.0.3` from commit `4a943cfd`, the build fails with the following
output:

Note: switching to 'FETCH_HEAD'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 14f468c improved arity control for JOIN
```

Maybe the upstream Snap maintainer changed the repo commit where the tag
`v7.0.3` points at after the Guix package definition was updated?

Thanks!

It looks like so, because I'm pretty sure I tested it when I bumped it
to 7.0.3.

In any case, I updated it to 7.0.5. Hopefully, it now builds. Thank you
for the report.

Since 'snap' has a history of mutating tags in-place, maybe it would
would be a good idea to replace (string-append "v" version) with the
actual commit string (and not a tag name), to avoid future breakage
and help "guix time-machine" users?

Greetings,
Maxime

Personally, I would change to commits after the first time it happens,
to avoid having to keep count.

Anyway, I asked upstream <https://github.com/jmoenig/Snap/issues/2966>
whether this will happen again.  Let's wait for a response?

Greetings,
Maxime.

Upstream answered. It was an exception. So I guess all is fine.

Thanks for bringing it up to upstream.
